Fabrication of thiol-surfaces using aromatic self-assembled monolayers

Self-assembled monolayers (SAMs) formed from [1,1'-biphenyl]-4,4'-dimethanethiol and [1,1';4',1'-terphenyl]-4,4' -dimethanethiol on Au are characterized by X-ray photoelectron spectroscopy (XPS), high-resolution XPS, infrared reflection absorption spectroscopy and other measurements. The aromatic dithiols are well suited for the fabrication of thiol-terminated SAMs.
